Bought some new 2400 g.skill today and am on z77 chipset board but have the older 2600k cpu on here, noticed later after buying this ram that it is recommended for i7 3770 and i5 3750 cpus. Manually set the bios settings just to get it to run at 2133 @ 1.65 volts(XMP won't work).

Was wondering if anyone else has run into this before and has some bios tweaks to get this ram running @ 2400 speed on this 2600k?

2400mhz ram on a 1155 platform isn't going to gain you ANY benefits whatsoever and the 1155 platform prefers ram to run at 1.5v

I know is no real world benefit for 2133-2400 speed increase but was hoping to get it running at its rated speed anyway. Have never been into playing it safe with my parts, If my cpu dies before its time no big deal, been itching to get a 3770k since it came out, lol. My 2600k doesn't even know what default 3.4 is...

My motherboard is on the rams approved list, will play with the timings today to see what I can get.

am running the newest asus bios for this gene v board, did try running the xmp in the bios settings but system would just keep restarting in a loop with no posting or not restart at all, had to pull the plug a few times to get er going again with xmp set, once I set it too 2133 manually it would boot up with voltage left @ 1.65 and that is the voltage of my previous ram also that I had in that was bought for the z68 chipset board I had previously till upgrading to z77.

So @ 2400 speed with 1.65 volts she wont post and sometimes not even restart after saving the bois with xmp set and exit idea. Previous mem @ 2133 worked with xmp set np.

this note was posted on the site for my ram : Note : Recommended Intel Core i7-3770K processors & Core i5-3570K processors for best performance

Wasn't sure what that meant by best performance idea, 2400 running at 2133 for the 2600k? Or some manually set timmings in bios @ 2400 speed on this 2600k?

After trying allot of different settings in bios have settled in at 2133 with profile 2 xmp setting, that seems stable and the best I am able to get so far. 2400 seems out of reach for this 2600k afaik. Guess is why they have a note that 3770 and 3570 is recommended for best performance (ie:2400 speed).

On a side note figured if I am running at 2133 would add back in my 8 gig pair of 2133 but couldn't get the system to post at all, had to remove them.

Am not disappointed with the purchase anyway, it seems that everything is pushing me to buy the new chip pci-e 3.0, 2400 speed and a bit more bandwidth on the pipe. All things considered still isn't worth the $350 for a new chip I don't think.
